ELEVATOR FOR cRAIN-sl-:PARAToRsl SPECIFICATION forming part of Letters Patent No. 402,522, dated April 30, 1889.

YApplication led September 10, 1888. Serial No. 285,000. (No model.)

To all whom it may concern:

Be it known that I, STA'CY B. I-IART, a citif zen of the United States of America, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Elevators for Grain- Separators, of which the following is a specification.

Referring tothe accompanying drawings, in which similar reference-letters indicate the same or corresponding parts, Figure 1 is a side elevation of the elevator-tube; Fig. 2, a partial longitudinal section of the same; Fig. 3, a partial section showing a constructional modification; Fig. 4, a side elevation of the lower end of the elevator-tube With a portion broken away to show the mode in which the adjustable grain-chuteis applied Fig. 5, a side elevation of the same, showing in plan the feed-Y opening and the flange around it; Fig. 6, a plan of the metal sheet employed for the grainchute; Fig. 7, a view of said sheet with its corner folded or removed to adapt it to be applied so as to adjust the lateral inclination of the chute; and Fig. 8, a horizontal section in line @c :1; of Fig. l, illustrating the oblique application of the chute.

stantially as hereinafter described and claimed, designed to enable the elevator to be adjusted to the height of the separator, and, further, in improved means for connecting the elevator with the grain-spout of the separato r.

In the elevators which are employed in connection with the combined thrashing and screening machines termed grain-separators the tube through which the grain is y raised is almost necessarily extended several feet above the top of the separator-frame, in order to properly deliver the elevated grain into the transverse conveyer or the weighing attachment.

Grain-separators varying in the height of their'fram es and in the relativedimensions and arrangement of their parts are constructed and sold in large numb ers by different manufacturers without being provided with an elevator or weighing attachment, and, on the other hand,

large numbers of the latter are made and sold to be applied by farmers to their old separatorsralready in use. In consequence of these facts two serious practical dificulties arisetolwit, first, the varying height of the separator-frames renders it impossible to adopt any fixed standard of length for the elevatortubes necessary to be used with the weighing attachments, but tubes of different length have to be provided to suit the different separators, and thus the manufacturer or dealer is obliged to carry a large stock to meet the requirements of the trade, and, secondly, in many'separators on the market the discharge end of the grain-spout is so near to one of the supporting-wheels of the'machine that therev is not suflicient room between them to accommodate the lower end of the elevator-tube,

which in such case must be arranged out of .culty common to all cases, even where the separators and elevators are made together or fitted 'to each other in the manufacturers shops, arises from the fact that the elevatortubes project so far above the separatorframe when on the machine as to be'liable to comein contact with the top of the covered bridges or of the barn doorway, rendering it impossible to get the machine through without removing the elevator.

The object of my present invention is to remedy these several difficulties by providing an elevator-tube which can be made of one standard size and pattern and easily adjusted to iit any of the separators in use, and which can be readily lowered to permit the combined machine to pass through bridgeways or doorways without obstruction, whenever` occasion arises therefor. In the drawings, A is the elevator-tube constructed in two or more sections, a a', capable of sliding or telescoping one in another. I prefer to construct these sections of sheetiron in round tubular form, and to adapt the form of the elevator-buckets thereto. The 5 lower section, c, is intended to be fixed, and the section a above to slide up and down on it, a suitable power device-for example, a rack, b, and pinion b operated by a crank, b2, attached, respectively, to the lower and 1o upper sections, as shown in Figs. l -being provided to enable the upper section to be readily and easily slid up and down on the lower one. In attaching the device to a separator the lower section is to be first secured in place and the upper section then slid up 0r down to the required eXtent and fastened in its adjusted position. Y

Any suitable fastening device may be employed for this purpose; but I prefer to slit 2o the outer section at and near its end, as shown at a2, and to provide it with a simple strap or band, c, passing around its end and having a clamp-screw, c', which may be loosened to permit the two sections to be con` nected or adjusted and then tightened t0` clamp them firmly together.

The interior of the elevator-tube is divided j by a longitudinal partition, d d', arranged between the ascending and descending portions 4o elevator-tube thus constructed can be easilyl adjusted to fit the frames of all the different separators in use, and its' upper end can readily be lowered out of the way when the machine is to be taken through a low passageway. The drive chain, when of the ordinary constructions now in use, can be easily adapted to the adjusted tube by inserting or removing one or more links, and can be tightened up by a slight additional adjustment of 5o the tube-sections, this ability to adjust the tension of the chain at any time constituting another valuable advantage arising out of my improvement.

In this class of machines the grain-spout g delivers the screened grain from the sepa- 'rator to the elevator through an opening, h,

in the side of the elevator-tube at or near its lower end. Where, in attempting to apply an elevator to an old separator, it is found 6o that the supporting-wheelw of the latter renders it impracticable to arrange the opening h of the elevator-tube directly in line with the grain-spout g, the tube must be arranged in the most available position, and an ob- .65 lique or diagonally-arranged chute must be shown in Figs. 4, 5, and 8, andl furnish to dealers or users, in connection with each elevator, a rectangular piece of sheet metal, I, Fig. 6, preferably provided with rivet-holes ft2, corresponding to those in flange i.

If the separator upon which the elevator is to be used is such as to permit the opening 7L to come directly in line with the grain-spout, then the ends of the sheet I are to be folded on its body, as indicated by the dotted lines in Fig. G', and it is simply bent to fit the concave side of the flange c' and riveted to the latter and to the grain-spout. If the opening h does not come in line with the spout, then the ends of the sheet are to be folded diagonally upon its body, as shown by the dotted lines in Fig. 7, after which it is bent to fit the fiange t' and extend obliquely there- 9 from to the grain spout, as represented in Fig. S.

By this Simple device I enable the elevator to be readily applied to any separator, and dispense with the necessity for carrying in stock alarge quantity of specially-co1lstructcd chutes of different patterns.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. An elevator-tube, A, made in sections c d', adapted to telescope, incombination with a contained partition made inA overlapping sections d d and with means by which the sections a a and CZ CZ may be fastened in their adjusted positions with relation to each other, substantially as described.

2. An elevator-tube, A, having a semi-annular flange, around the lower edge of the grain -receiving opening h, provided with holes t" to receive the screws or rivets by which the grain-chute is attached tothe elevator, substantially as described.

3. The combination 0f the elevator-tube A, having the semiannular iiange fi arranged around the lower edge of the grain-opening h, provided with holes z" and permanently connected to the elevator-tube, and arectangular piece of sheet metal adapted to be folded and applied, substantially as and for the purpose described.
